What is your SEO workflow?

Hi everybody,
Here is my goal:

1. Build a Handyman Site in Las Vegas, NV
2. Do SEO for that.

I am at the first step now.

Question:

What tools do you use: free / paid for backlink checks, etc.?

What is the checklist for me at this point?

My site is WordPress and I optimize content, title, keywords, etc.
